DETAILED DESCRIPTION OF THE EMBODIMENTS

Selected embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

Referring initially to the FIG. 1, a magnetic tower pet toy 10 (also referred to as the pet toy 10) is illustrated in accordance with a first embodiment. The magnetic tower pet toy 10 includes a base 12, a pole member 14, a first arm 16 (an arm member), a second arm (an arm member) 18, a third arm 20 (an arm member) and a cap 22.

The base 12 is preferably formed from molded plastic or any other suitable material, and has a bottom portion 30, a plurality of post-like sections 32 (hereinafter referred to as post sections 32), an upper annular ring 34 and an extension 36 extending from the bottom portion 30. The bottom portion 30 is a basically a weight supporting structure that encloses a weight W, as shown in FIG. 8. As shown in FIGS. 1, 2 and 3, the base 12, and in particular the bottom portion 30, is preferably formed with a semi-spherical, hemisphere or other rounded shape. More specifically, the bottom portion 30 can thus enable the pet toy 12 to wobble or rock in various directions.

The post sections 32 of the base 12 are ribs or spoke-like structures that curve and extend upward from the bottom portion 30 to the upper annular ring 34. The bottom portion 30, the post section 32, the upper annular ring 34 and the extension 36 can be formed as a single unitary, monolithic element, or, alternatively, can be assembled from separate members that are fixed to one another by fasteners (not shown), fused or adhered to one another by an adhesive material, depending upon the manufacturing techniques used to manufacture the magnetic tower pet toy 10.

The extension 36 extends upward from the bottom portion 30 and is encircled by the upper annular ring 34. Recesses, openings or open areas are defined between adjacent ones of the post sections 32, and also around the extension 36 above the bottom portion 30. Further, the upper annular ring 34 is spaced apart from the extension 36, thereby defining an upper annular gap therebetween open to the recesses defined between the post sections 32 and the extension 36. The open areas and annular gap provide an overall decrease in weight of the base 12. Moreover, lower inner parts of the post sections 32 serve as internal ribs that extend radially inward from the post sections 32 to the extension 36 increasing overall rigidity of the base 12 without significantly increasing the overall weight of the base 12. The weight W, as shown in FIG. 8, is located at a bottom-most area of the bottom portion 30 of the base 12. The bottom-most area of the bottom portion 30 is a central weight supporting portion of the base, retaining the weight W therein. The weight W serves to maintain the pet toy 10 in an upright position. Further, the weight W is dimensioned and positioned such that gravity urges the pole member 14 toward an upright vertical orientation.

The extension 36 is generally cylindrical and extends upwardly from the bottom portion 12. In an alternative embodiment, the extension 36 can have a center portion that has an outer diameter that is less than its upper and lower ends. The extension 36 defines an upper surface 36 a with a base magnet M_(B) fixed thereto or encased therein. The extension 36 is preferably centered between the plurality of post sections 32 and centered relative to the upper annular ring 34.

The pole member 14 can be plastic or any other suitable material and extends from the extension 36. More specifically, the pole member 14 is inserted into an opening 36 b (FIG. 8) formed in the extension 36. The pole member 14 is basically a rod with a round or cylindrical shape and has an outer diameter that is significantly less than the diameter of the extension 36. The cap 22 is dimensioned and sized to snuggly fit around the top end of the pole member 36 such that the cap 22 prevents the first arm 16, the second arm 18 and the third arm 20 from accidently being removed or coming loose from the pole member 14.

As shown in FIGS. 1 and 3, the first arm 16, the second arm 18 and the third arm 20 have differing lengths. Specifically, as shown in FIG. 3, the first arm member 16 has a first overall length L₁, the second arm member 18 has a second overall length L₂ that is less than the first overall length L₁, and the third arm member 20 has a third overall length L₃ that is less than the first overall length L₁ and greater than the second overall length L₂.

Other than their respective overall lengths, the first arm 16, the second arm 18 and the third arm 20 each have the same features. For example, the first arm 16 includes an opening 16 a and a first magnet M₁. The second arm 18 includes an opening 18 a and a second magnet M₂. The third arm 20 includes an opening 20 a and a third magnet M₃.

The opening 16 a of the first arm 16 is centered relative to the first overall length L₁ of the first arm 16. Further, the first magnet M₁ has an annular shape with a central aperture that encircles and is co-axial with the opening 16 a. Similarly, the opening 18 a of the second arm 18 is centered relative to the second overall length L₂ of the second arm 18, and the second magnet M₂ has an annular shape with a central aperture that encircles and is co-axial with the opening 18 a. As well, the opening 20 a of the third arm 20 is centered relative to the third overall length L₃ of the third arm 20, and the third magnet M₃ has an annular shape with a central aperture that encircles and is co-axial with the opening 20 a.

When the first arm 16, the second arm 18 and the third arm 20 are fully assembled to the base 12 and the pole member 14 as shown in FIGS. 1-3, the pole member 14 extends through each of the openings 16 a, 18 a and 20 a. Further, as shown in FIG. 3, when fully assembled, the polarity of each of the magnets M₁, M₂ and M₃ alternate. In other words, the north pole N of the base magnet M_(B) faces the north pole of first magnet M₁, the south pole S of the first magnet M₁ faces to the south pole S of the second magnet M₂ and the north pole N of the second magnet M₂ faces the north pole of the third magnet M₃. Consequently, the first arm 16, the second arm 18 and the third arm 20 are oriented such that the base magnet M_(B) repels the first magnet M₁, the first magnet M₁ repels the second magnet M₂, and the second magnet M₂ repels the third magnet M₃. As a result, in the absence of other forces acting on the base 12, the first arm 16, the second arm 18 and the third arm 20, the base 12, the first arm 16, the second arm 18 and the third arm 20 are all spaced apart from one another along the pole member 14 due to the repelling forces of the magnets M_(B), M₁, M₂ and M₃.

Each of the first arm 16, the second arm 18 and the third arm 20 is preferably made of plastic, but can be made of other light-weight materials. Respective ones of the magnets M₁, M₂ and M₃ are centrally installed or encased in the plastic material. Further, the first arm 16 includes extending portions 16 b that extend in opposite directions away from the first magnet M₁. The first overall length L₁ is measured end to end between the extending portions 16 b. Open ends of each of the extending portions 16 b are sealed with removable plugs or covers 40.

The second arm 18 includes extending portions 18 b that extend in opposite directions away from the second magnet M₂. The second overall length L₂ is measured end to end between the extending portions 18 b. Open ends of each of the extending portions 18 b are sealed with removable plugs or covers 40.

The third arm 20 includes extending portions 20 b that extend in opposite directions away from the third magnet M₃. The third overall length L₃ is measured end to end between the extending portions 20 b. Open ends of each of the extending portions 20 b are sealed with removable plugs or covers 40.

It should be understood that the openings 16 a, 18 a and 20 a are dimensioned such that each of the first arm 16, the second arm 18 and the third arm 20 can freely rotate or spin about the pole member 14 and relative to the base 12.

As shown in FIGS. 6 and 7, the covers 40 can be removed from the ends of the first, second and third arms 16, 18 and 20 and optional connecting members 50 can be inserted into the open ends of the first, second and third arms 16, 18 and 20. The connecting members 50 includes various dangling objects 60 or other play toys. As is shown, the connecting members 50 can be frictionally fit within the openings at opposite ends of the first, second and third arms 16, 18 and 20. The objects 60 attached to the connecting members 50 can have strings that attach thereto to enable the objects 60 to swing about freely or simply connect to the first, second and third arms 16, 18 and 20.

In the depicted embodiment, the first, second and third arms 16, 18 and 20 are shown installed to the base and the pole member 14. However, it should be understood from the drawings and the description herein that the pet toy 10 an be provided with only a single arm, such as only one arm selected of the first, second and third arms 16, 18 and 20. Alternatively, a plurality of additional arm members can be disposed on the pole member 14. In such a configuration, each arm member includes a magnet disposed in the central portion thereof. Thus, each magnet is repelled by the magnet below it, enabling each arm member to freely rotate around the pole member.

To assemble the toy, the pole member 14 is inserted into each of the openings 16 a, 18 a and 20 a of the first, second and third arms 16, 18 and 20. One or more arm members are disposed on the pole member 14 by inserting the pole member 14 through the openings 16 a, 18 a and 20 a, such that each adjacent magnet repels the magnet above it. The cap member 22 is then friction fitted or otherwise securely attached to the end of the pole member 14, preventing accidental removal of the first, second and third arms 16, 18 and 20.

Accordingly, an animal can play with the toy by batting or hitting the objects 60 and or the arm member with a paw thus causing the arm member to freely rotate around the pole member. The magnets causing the arm member to be positioned away from the end of the extension enable an almost frictionless rotation of the arm member. Moreover, the arm member can move longitudinal up and down on the pole member 14 (i.e., closer and further from the base magnet M_(B)), and/or in a pivoting manner (i.e., one arm member moving downward while the opposite arm portion moves upward). The animal's actions also may cause the rounded base 12 to cause the toy to wobble or oscillate. All of these movements can prolong engagement and interest in the toy.

While only selected embodiments have been chosen to illustrate the present invention, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made herein without departing from the scope of the invention as defined in the appended claims. For example, the size, shape, location or orientation of the various components can be changed as needed and/or desired. Components that are shown directly connected or contacting each other can have intermediate structures disposed between them. The functions of one element can be performed by two, and vice versa. The structures and functions of one embodiment can be adopted in another embodiment. It is not necessary for all advantages to be present in a particular embodiment at the same time. Every feature which is unique from the prior art, alone or in combination with other features, also should be considered a separate description of further inventions by the applicant, including the structural and/or functional concepts embodied by such features.
